Problems solved by technology

[0004] Most of the existing display screens are fixed planar display devices, and the area of ​​the screen remains unchanged, which can meet the full display requirements. However, in the case of large venues or publicity needs, people in the distance cannot see the display screen clearly. In this case, if the display screen is enlarged, people in the distance can see the display screen of the display device. The existing retractable LED display device can be stretched and stretched in one direction. Although this stretching method can enlarge the LED display The spacing between units will enlarge the display content, but if it is not proportionally enlarged, the display content will be distorted

Embodiment 1

[0068] Example 1, such as Figure 9 As shown, it also includes a load-bearing steel cable 300 and a support, and the two ends of the load-bearing steel cable 300 are fixed to the support in a horizontal shape; it also includes a left pulley 410, a right pulley 420 and a two-way pulley 400 fixedly installed on the support. The two-way pulley 400 is located above the central point of the load-bearing steel cable 300, and the left pulley 410 and the right pulley 420 are respectively located on the left and right sides above the load-bearing steel cable 300;

[0069] The top side of the scaling plane is defined as the top side, and the adjacent surface connecting portion A of the top side is equipped with a pulley B, and the scaling plane is hung on the load-bearing steel cable 300 through the pulley B, and the scaling plane is passed through the pulley B is slidably installed on the load-bearing steel cable 300;

[0070] It also includes a first left steel cable 510 and a first ...

Embodiment 2

[0071] Example 2, such as Figure 8 As shown, it also includes a second left cable 530 and a second right cable 540, the end of the second left cable 530 is fixed to the pulley B at the left end of the zoom plane, and the end of the second right cable Fixed on the pulley B at the right end of the scaling plane, the second left steel cable 530 is installed on the left pulley 410, the second right steel cable 420 is installed on the right pulley 420, and the second left steel cable is pulled upward Cable 530 and upward pulling the second right cable 540 can make the zoom plane unfold; or along the left pulley 410 and right pulley 420, pull the second left cable 530 to the right and pull the second The right cable 540 can expand the zoom plane.

[0072]The principle of this scheme is to pull and retract the zoom plane through pulleys and cable traction. The load-bearing cable 300 is used as a device for suspending the zoom plane, so that the pulley on the top edge of the zoom pl...

Abstract

An extensible LED display device comprises at least two extensible units and LED display units mounted in the extensible units. The extensible units are mutually connected to form a zooming plane, each extensible unit is composed of a plurality of triangular members and multiple hinging members, a triangle virtually formed by three angular vertexes of each triangular member is an isosceles triangle, each triangular member is provided with a meso-position hinging portion, distances from the corresponding meso-position hinging portion to each angular apex are equal, and the meso-position hinging portions of each two triangular members are rotatably crossed and connected through one hinging member to form a triangular set; each meso-position hinging portion is mounted with one LED display unit, and each LED display unit is mounted on the front of the corresponding extensible unit and used for displaying texts, images or video. The extensible LED display device can amplify display area by equal proportion so as to enable people in the distance to see display content more clearly, and area can be increased by 85% after being amplified by the device.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a telescopic LED display device. Background technique [0002] As a high-tech product, LED display technology has attracted people's attention. It is not only used for lighting, but also used in many fields as a display technology. Has become a mainstream product in the electronics industry. [0003] LED display technology is a display device composed of light-emitting diode dot matrix modules or pixel units. LED display technology has experienced the development process from single-color, two-color graphic display screens, to image display screens, and to today's full-color video display technology. . The level of ultra-high-brightness full-color video display that has been achieved so far can meet the requirements of various application conditions. my country's LED display technology has formed an industry with considerable development potential so far. [0004] Most of the existing ...
